# @modelcontextprotocol/ext-apps MCP Extensions Apps SDK. ## Installation This repo is in flux and isn't published to npm (when it is, we'll probably use the `@modelcontextprotocol/ext-apps` package). Please install it from git for now: ```bash npm install git+https://github.com/modelcontextprotocol/ext-apps.git ``` ## Development Notes ### Build tools in dependencies The build tools (`esbuild`, `tsx`, `typescript`) are in `dependencies` rather than `devDependencies`. This is intentional: it allows the `prepare` script to run when the package is installed from git, since npm doesn't install devDependencies for git dependencies. Once the package is published to npm with pre-built `dist/`, these can be moved back to `devDependencies`.
